A nurse is caring for a client who is dying of metastatic breast cancer. She has a prescription for an opioid pain medication PRN. The nurse is concerned that administering a dose of pain medication might hasten the client's death. Which of the following ethical principles should the nurse use to support the decision not to administer the medication?

Rationale:

A. Rotavirus (RV) vaccine is an oral live attenuated preparation designated strictly for young infants to prevent severe gastroenteritis. The standard administration window closes completely at 8 months and 0 days of age. Administering this vaccine to a 1-year-old child is clinically inappropriate and contraindicated due to insufficient safety data.

B. Human papillomavirus (HPV) vaccine is a recombinant preparation formulated to protect against oncogenic viral strains linked to cervical and anogenital carcinomas. Routine administration is universally deferred until late childhood or early adolescence, beginning between ages 9 and 12. It is not indicated or immunologically useful for a 1-year-old patient.

C. Measles, mumps, rubella (MMR) vaccine is a live attenuated viral immunization routinely scheduled between 12 and 15 months of age. Administering this vaccine at 1 year of age is clinically correct because the infant is biologically capable of mounting an adequate antibody response. This timing prevents outbreaks of these highly contagious diseases.

D. Varicella (VAR) vaccine contains live attenuated varicella-zoster virus designed to stimulate adaptive immunity against chickenpox and its neurological or systemic sequelae. The initial dose is officially scheduled for pediatric patients between 12 and 15 months of age. A 1-year-old child must receive this vaccine to optimize primary infectious defense.

E. Diphtheria, tetanus, and acellular pertussis (DTaP) vaccine represents a combined toxoid and inactivated subunit series protecting against severe bacterial pathogens. The fourth dose is normally scheduled between 15 and 18 months of age. However, clinical guidelines permit early administration at 12 months provided at least 6 months have elapsed since dose 3.

A. Maintain the head of the bed in a flat position for 30 min following medication administration: This option is incorrect because after administering medications through an NG tube, it's crucial to elevate the head of the bed to at least 30 to 45 degrees to minimize the risk of aspiration. Keeping the head of the bed flat increases the likelihood of reflux and aspiration of medication.
B. Mix the three medications together prior to administering: This option is incorrect because mixing medications without specific instructions from the healthcare provider can lead to potential interactions or alterations in the effectiveness of the drugs. Each medication should be administered separately to ensure accurate dosing and prevent potential adverse effects.
C. Rush the NG feeding tube with 30 mL of water immediately: This option is incorrect because while flushing the NG tube with water after medication administration is necessary to ensure that the medications reach the stomach and to prevent tube occlusion, the recommended volume for flushing is typically 30 to 60 mL, not just 30 mL. Using a larger volume of water helps ensure thorough flushing of the tube.
D. Dilute each medication with 10 mL of tap water: This is the correct action. Diluting each medication with 10 mL of tap water is a standard practice to ensure proper administration through an NG tube. Dilution helps prevent tube occlusion and irritation of the gastric mucosa, reducing the risk of complications such as clogging of the tube or local irritation. Additionally, diluting the medications facilitates their passage through the tube and into the stomach, optimizing absorption and effectiveness while minimizing the risk of adverse effects.
